Anabolic steroids can cause the development of acne. However, the extent to which it is experienced can be due to a number of varying factors, with the particular steroids and exact dosages used being primary. The skin´s sebaceous glands have a particularly high affinity to Dihydrotestosterone, which is an androgen the body naturally produces from testosterone via the enzyme 5-alpha Reductase. Increased sebaceous gland activity promotes oily skin which can combine with bacteria and dead skin (normal wear and tear) eventually causing pores to become clogged more quickly than the body can cleanse them. This of course, is preventable by using only particular steroids, cleansing the skin regularly, and perhaps using a topical anti-androgen.
In general it has been found that oral steroids are more likely to prove detrimental to cardiovascular health than injectable forms of non C-17 alkyl steroids. In this regard it is important to point out that estrogen is actually known to have a positive effect on cholesterol levels, enhancing HDL levels, and keeping LDL levels under control. It is when aromatase inhibitors in ancillary compounds come into play during the steroid cycles that the individual is at risk of cardio-vascular diseases owing to estrogen levels being subdued. Further, it has been seen that when the individual is committed to a healthy diet that supports desired cholesterol levels during the steroid cycle , the risk of cardiovascular disease arising from steroid use can be kept under control.
